KNOTTING MECHANISM FOR GRAiN-BINDERS.

SPECIFICATION forming part of Letters Patent No.352,811, dated May 10, 1887.

Application filed June 17, 1895. Serial No. 168,925. (No model) To all whom, it may concern.-

Be it known that 1, Joan F. APPLEBY, of Minneapolis, Minnesota, have invented certain Improvements in Knotting Mechanisms for Grain-Binders, of which the following is a specification.

My improvements relate to the type of k notting apparatus in which the knotter-operating wheel has on the side with the operatinggcar a single cam'groovc, which is the source of motion for the various devices which, in conjunction with the rotating knotting-bill, form the knot, sever the binding-cord between the knotting-bill and the gripping device, and strip the knot from the knotting-bill.

My present invention consists, essentially, in the combination, with the knotteuopcrating wheel having gearsegment and cam on the same face or side of the wheel, of a knotter-shaft and a single rocking lever, through which motion is transmitted from the cam for the operation of the devices,respectively, for gripping the bindingcord, for severing the binding-cord between the knotting-bill and the grippi11g-disk,and for stripping the knot from theknotting-bill. By reason of this construc tion and combination the knotting, clamping, severing, and stripping devices are located and operated on one side of the plane of theknotteroperating wheel, and a compact arrangement of parts is obtained, especially desirable in low binders.

It is an incidental feature of my invention that the motion for operating a tucker for tucking the binding-cord under the knottingbill is also transmitted from the cam on the knotter-opcrating wheel by the said rocking lever.

The accompanying drawings of knotting apparatus containing my improvements are as follows:

Figure l is an elevation, affording a view of the cam-groove in the face of the knotter-opcrating wheel, and, for present convenience, may be assumed to be a front elevation of the apparatus. Calling Fig. 1 a front elevation,

Fig. 2 is a left-hand side elevation, partly in section; Fig. 3, a rear elevation with the knotter operating wheel and its shaft removed; Fig. 4, a horizontal section through i the line :0 w on Fig. 2; and Fig. 5, a right-hand side elevation, partly in section, but showing the apparatus upside down for convenience of showing certain of the parts represented in Figs. 2, 4, and 5 in the same vertical alignment.

Referring to the drawings, it will be seen that the knotter-opcrating wheel A is pro vided upon its periphery with a projecting. flange, upon the face of which are formed the teeth of asegment or bevel gear, A, which at the proper time during the rotation of the camwheel engages and rotates the bevel-pinion B, affixed to the upper end of the k nottershaft B.

The face ofthe knotter-operating wheel upon which the segment-gear A is formed is provided with the cam-groove (l, for operating the rocking lever D, provided at the end of its laterally-projecting arm D with the antifriction roller D, for engaging the cam groove 0. The shaft A of the knotteroperating wheel has its bearing in the upper end of the principal standard a of the frame.

The rocking lever D is cast in one piece with or otherwise affixed to the horizontal rock-shaft I), which is provided with a bearing in the tubular boss to, cast on the standard a. The lower end, d, of the downwardly-projecting arm d of the rocking lever enters the space between the teeth 0 c, projecting upwardly from the horizontal sliding plate E. Thus when the lever D is rocked it imparts reciprocating sliding motion to the plate E. The plate 1*] is provided with suitable guides, F F, by which its path of motion is defined. The knife E is mounted upon a standard, E erected upon one side of the plate E, and during the reciprocating motion of the plate passes between the knotting-bill b and the grippingdisk G.

Upon the side opposite the knife the plate E is provided with a vertical flange, E", the top of which serves as a cord-guide for supporting the binding-cord after the binder-arm has retired and during the process of forming the bundle. The flange E terminates on one side of the relatively narrow mouth of the notch e in the plate E. There is erected at the other side of the mouth of the notch e the tuckingfinger c", the edge of which, as will be seen, inclines forward slightly over the mouth of the notch e, and is thereby adapted to guide the binding-cord into the notch 6, so that during the forward movement of the plate E the binding-cord, extending from the knotting-bill to the bundle, is tucked nearly under the knotting-bill.

As will be seen, when the knot is formed, the binding-cord extends from the knottingbill through the notch c to the bundle, and hence by the backward movement of the plate E is stripped from the knottingbill. As the cord arm retires, the binding-cord, the end of which has been gripped in one of the notches of the gripping-disk G, is deposited upon the top of the flange E, as before.

The arm (1 of the rocking lever D is provided with the laterallyprojecting stud d upon which is hung the driving-pawl g,wl1-ich engages the teeth of the ratchet-reel g, affixed 'not need especial description herein, as the present invention relates to the employment of a single rocking lever for taking motion from a single cam-groove in the knotter-operating wheel, and by means of the driving-pawl 9 operating the gripping device, and by means of the downwardly-projecting arm d reciproeating-the plate E, and thereby operating the knife for severing the binding-cord and the strippingdevice for stripping the knot from the knotting-bill.

I claim as my invcntion 1. In a knotting apparatus for grain-binders, the combination, substantially as herein set forth, of a knottcr-operating wheel provided with segmental gear and a cam-groove on the same face or side of the wheel, a knotter-shaft carrying a knot-ter-bill, a single rocking lever, v

a gripping device, a pawl pivoted to said lever for operating said device, a reciprocating plate operated by said rocking lever and carrying a knife for severing the binding-cord between the knotting-bill and the grippingdisk, and a stripping device for stripping the knot from the knotting-bill, substantially as described.

2. The combination, as herein described, of

the knotter operating wheel A, provided with segment-gear A and cam-groove G on the same side of the wheel, the knotter-shaftB, the

rocking lever D, the reciprocating sliding plate E, provided with cord-guide E and with notch e, and the tucking-finger 6 as and for the purpose set forth. 7

3. The vibrating carrier, in combination with the cord-guide and stripper, the cordcutter, and the actuating-pawl of the cordholder, all connected with and operated by the said carrier, substantially as and for the purposes set forth.
